Custodial sentence achieved for a malicious insider

Client Background

A prestigious national museum in the UK, safeguarding historical artefacts and sensitive data, engaged Cyber Overwatch after the trustees reported a cybersecurity incident to law enforcement.

Challenge

Following a concerning security incident reported to the cyber police, the museum trustees urgently required expert assistance to identify and mitigate the threat swiftly, discreetly, and comprehensively. Through our networks and technical surveillance countermeasures background we were asked to assist.

Cyber Overwatch’s Response

Cyber Overwatch rapidly deployed, conducting a thorough investigation of the museum’s IT infrastructure. Our team identified unusual patterns of access to sensitive data and irregular remote access tools.

Utilising advanced behavioural analysis and detailed forensic techniques, Cyber Overwatch uncovered evidence pointing clearly to an internal source rather than external cybercriminals.

Resolution

Cyber Overwatch provided the trustees and cyber police with a detailed evidence pack, clearly identifying a malicious insider. This comprehensive evidence package included precise logs, timestamps, and detailed records of unauthorised data transfers, proving beyond doubt the individual's culpability.

The robust evidence supplied by Cyber Overwatch was critical in the subsequent police investigation, ultimately leading to the perpetrator’s conviction and custodial sentence under the UK Computer Misuse Act.

Ongoing Prevention

Post-incident, Cyber Overwatch collaborated with the museum trustees and security teams to enhance internal cybersecurity measures. Our recommendations included tighter access controls, improved internal monitoring systems, and reinforced staff awareness training to prevent similar breaches.

Continuous behavioural analytics and proactive threat detection measures were implemented, significantly bolstering the museum’s defences against potential future insider threats.

Outcome

Cyber Overwatch’s swift, detailed investigation and clear evidence provision enabled decisive action against the malicious insider, protecting the museum's valuable data and reputation. The strengthened cybersecurity posture has significantly reduced future risks, ensuring the museum remains secure and trusted.
